I would like to configure my Cisco switch and router. The switch that I have is a Cisco Catalyst 1900. The router that I have is a Cisco 2501. I also have a Cisco PIX Firewall. I am using the Rollover cable. I connect one end of the rollover cable to the Console port on the Cisco device, and the other end into an RJ45 to DB-9 adapter. Then, I plug that adapter into the serial port on my computer. There is only 1 serial port on my computer, and it is attached to the motherboard (onboard). When I open HyperTerminal on my computer, all I see is a blinking cursor. I tried pressing enter a few times, but that didn't do anything. I know that the serial port on my computer works because I see it listed in the Device Manager, as Communications Port (COM1). I tried to console into the Cisco equipment on another computer, but that didn't work either. I tried consoling into 3 different Cisco devices, but nothing is working. I know that the Rollover cable is the right one because the pins are opposite, on both ends of the cable. What can I do to fix this problem that I am having?
